Region-based memory management and GC?

[Jon Degenhardt]

Have there been any investigations into using region-based memory 
management (aka memory arenas) in D, possibly in conjunction with 
GC allocated memory? This would be a very speculative idea, but 
it'd be interesting to know if there have been looks at this area.

My own interest is request-response applications, where memory 
allocated as part of a specific request can be discarded as a 
single block when the processing of that request completes, 
without running destructors. I've also seen some papers 
describing GC systems targeting big data platforms that 
incorporate this idea. eg.
